放射性方法在我国找寻油气藏中的应用进展

近年来,随着测量技术的完善和提高,应用放射性方法找寻油气田取得了明显进展。研制出了携带式微机化仪器设备。在野外工作中,开展了高精度、多参数的放射性测量。在室内工作中,利用放射性测量工作站对数据进行处理和解释。通过对一些油气田进行的综合研究和对放射性元素运移规律的模型实验,对放射性异常和油气藏的关系及异常形成机制有了新的认识。众多实例表明,放射性方法是一种简便、快速、经济、实用、安全的找油气方法,在石油勘探中可以取得良好的经济效益。

THE ADVANCES IN THE APPLICATION OF RADIOMETRIC METHOD TO THE PROSPECTING FOR OIL AND GAS ACCUMULATIONS

In recent years, with the improvement of the radiometric tecbnique, rema-rkable advances have been made in the application of radiometric method to the prospecting for oil and gas fields. Portable microcomputerized instruments and equipments have been developed. In field work, high-precision and multi-parameter radiometric survey has been carried out; in indoor work, radiome tric stations have been utilized to undertake data processing and interpretation. Through integrated investigation of some oil and gas fields and model experi mentation on migration regularity of radioactive elements, new understanding has been gained concerning the relationship between radioactive anomalies and oil-gas accumulations and the formation mechanism of anomalies. Lots of case studies demonstrate that radiometric method is a simple, convenient, rapid, economical, practical and safe method in search for oil and gas fields and will surely yield good economic benefits in petroleum exploration.
